I To all whom it'mag concern:

Be it known that we, HENRY Her/[Mons 1o vention, such as will enable others skilled in the art to which it appertains to make and use-the same. I

This invention relates to an improved combination reinforced cement tie including improved clamping means for the rail. carried by -the reinforcing means.

As an object of the invention it is the aim to provide an improved device of this nature comprising a cement body having a U-shaped metallic bar embedded therein, together with embedded rods for reinforcing the cement structure.

Another object of the invention is to provide the reinforcing U-shaped bar with a tie 26 plate, which may be either integrally cast.

with the bar or detachably connected, however, preferably integrally.

Another object of the in ention is to construct an elongated slot in the tie plate to receive the shanks of the bolts, which fasten the rail clamping late in place, there being a hollow portion helow the tie late to receive the heads of the rail clamping bolt.

In practical fields the details of construc- 36 tion may necessitate alteratio: falling within thescope of what is claimed.

The invention comprises further features and combination of partsfas hereinafter set forth, shown in the drawings and claimed.

Inthe drawings, Figure 1 is a view in erspective, of the improved cement rein- ?orced tie constructed in accordance with the invention. Fig. 2 is a longitudinal sectional view through one end of the tie. Fig. 3 is 4 is a sectional view on line of Fig.

2. v Fig. -5 is a transverse sectional view, showing the tie plate made separate from the reinforcing bar, the same bem fastened by;

a screw at each end of the tie p a however,

only one screw being shown. Fi 6 is a detail view of a portion of the rein? rcing bar, showing the tie plate as detached therefrom. Fi 7 is a detail view of the tie plate.

i eferring more particularly to thedraw ings, 1 designates the cement tie as a whole,

tie plate are recesses 13 substantially directly a sectional. view on line 3-3 of- Fig. 2.

Figs. 2 and3. To arrange each of the bolts 15- in position its. head is passed through the which comprises anelongated body having embedded therein U -shaped metallic bar 2,. the opposite sides 3 of which areprovided with lateral flanges 4 and 5 acting to hold the cement structure together, the cement of which also extends up between the opposite side portions of the metallic reinforcing bar,

as shown at 6. To further reinforce the ocment structure auxiliary reinforcing rods'7 are embedded therein, extending longitudi-x nally of the tie. Each end of the U-shaped bar is constructed with a raised portion 8 cast integrally with which is a tie plate 9.

.Beneath each tie plate 9, the raised portion is constructed with an elongated hollow 10, which is immediately below the elongatede: slot 11 of the plate. Adjoining the hollow 10 and positioned laterally thereof under the opposite each other, to'receive the head 14 of the bolt 15, the shanks of which extend upwardly through the rail clamping plates 16, and are provided with nuts 17. etweenthes'nuts 17 and-the rail clamping plates'16 9 a are coil springs 18, which are sufliciently I compressed or tensioned by the nut 17, so asto hold the clamping plates 16 securely in I place. However, owmg to the construction 7 of one side 19 of each aperture -through 35 which each bolt 15 passes,the rail clam ing' plates are allowed to yield alittle. ow ever, this yielding action is not so great that the-rails 20 ma y spread far enough to permit improper contact or rollin of the car wheels W on said rail, but just su ciently to-permit the rails to yield, incident to thewheels passing thereover, andthen allow the rails to reseat themselves. The rail clamping plates 16 are provided with recesses 21 on their under surfaces, to engage the base flanges of the rails; Each tie plate adjacent opposite sides of its elongated slot 11': substantially at, the center portion of the slot is provided with cutawayportions or recesses 22, topermit the heads 14 of the bolts 15 to pass therethrough, when arran g the-bolts, in

such wise that their sha s may pas. up

wardly through the slot, as clearly shown In 106 opposltescutaway portions of recesses 22, so that its head may engage the recesses 13, and then by novinig each bolt to a lateral positionfas shownin Fig. 2, its shank will extend I vertically upward, so as to be passed through the rail clamping plate. After both rail clamping plates are so arranged, the rail is then placed in its proper position, and subsequently the plates 16 are moved toward each rail, and the nuts 17 tightened suf ficiently against said coil springs 19.

In Figs. 6 and 7 it will be observed that the tie plate may be made separate from the raised portion 8 of the reinforcing U- shaped bar. Therefore, in this case the tie plate is secured in place by screw bolts Q-l, onat each end of the tie plate. To avoid further illustration only one of said screw bolts is shown. 1

From the foregoing it will be observed that the reinforcing U-shaped bar bridges from one rail to the other, and constitutes means to withstand all lateral and longitudinal strains and weight incident to the rolling stock passing over the rails. In con structing the reinforced cement tie for practical use, it has been found practical as well as preferable to construct the tie plate as an integral part of the reinforcing bar, thereby not only insuring that all the strains are carried by the bar, but also to avoid rattling and preventing the eement'from cracking or crumbling. To further reinforce the cement body, each tie plate upon its under surface adjacent both ends thereof and upon opposite sides of the U-shaped reinforcing bar, is provided with downwardly extending angular members or projections 26, as shown clearly in Figs. and 4.

As shown in dotted lines in Fig. 2, it will be noted that each end of the elongated reinforcing rods 7 is provided with an angn lar end 7", to further reinforce the concrete structurec Jam nuts 27 are threaded upon the shanks of the bolts '15 to lock the nuts 17 in place. After arranging the bolts 15 in their proper places, with their shanks passing upwardly through the rail clamping plates, wedges 29 are tenmorarily used to engage between the rail clamping plates and the ends of the elongated slot '11, thereby acting to force the rail clamping plates firmly in contact with the rail. However, after the nuts 17 and the jam nuts 27 have been sufficiently tightened, to prevent undue movement of the plates 16 in lateral directions, that is, away from the rail, said wedges-are removed. after which each end of the slot 11 and the recesses 13 and the hollow 10 are filled with cement. To remove the clamping plate. 16 the nuts '17 and 27 are firstremoved, and then the coil springs, after which the rail may be lifted or raised, at the same time removing the clamping plate 16 0d the shanks of the bolt. To remove the bolts 15, it is only necessary to move the bolts toward the opposite recesses 92, and then extract them. In this case new bolts may be inserted in alike manner.

The invention having been set fortlnwluit is claimed as new and useful isz- 1. In combination with a cement tic body, a reinforcing core therefor comprising a U- shapcd metallic bar having an elongated tie plate adjacent each end upon the upper portion. said tie plate having an elongated slot to receive the shanks of rail clamping plate members. said U-shaped bar having an elongated hollow to receive the heads of said members. each slot having means to perm t the members to be arranged in said s ot.

Q. In combination with a cement tie bodY, a reinforcingcore therefor comprising a. metallic U-shaped bar having at each end a raised part. each raised part being provided with a tie plate having an elongated slot, said raised part having elongated recesses adjoining the slot to receive the heads of holding members of rail clamping plates, said holding members passing upwardly through the slot. the opposite walls of the slot adjacent its central portion being formed with recesses oppositely disposed to receive the heads of the holding member when arranging them in the slot.

3. ln con'ibination with a cement tie body, a reinforcing core therefor comprising a metallic U-shapcd bar having at ach end a raised part, each raised part being provided with a tie plate having an elongated slot, said raised part having elongated recesses adjoining the slot to receive the heads of holding members of rail clamping plates, said holding members passing upwardly through the slot, the opposite walls of the slot adjacent its central portion being formed with recesses oppositely disposed to receive the heads of the holding members when arranging them in the slot, said tie plate having downwardly extending angular projections at both ends and upon opposite sides of the bar to assist in reinforcing the cement structure, and auxiliary reinforcing tie rods in the cement body.
